M26A1 Fragmentation Grenade

Introduced to replace the MK II "Pineapple" grenade, the M26A1 "Lemon" Fragmentation Hand Grenade became common in Vietnam after 1965. Weighing 16 ounces (5 oz less than the MK II), the grenade could be thrown 40 meters by the average soldier and boasted an effective casualty radius of 15 meters. The M26A1 could also be fired up to 160 meters from a rifle using the M1A2 projection adapter. Like its predecessor, the M26A1 had a typical fuse time of 4 to 5 seconds.
